LIQUID DISPENSING MEANS William C. Buttner, Winnetka, Ill., assignor to The Bastian-Blessing 00.. Chicago, 111., a corporation of Illinois Application October 22, 1937, Serial Nos-170,420

'7 Claims.

This invention relates to a method and a device for dispensing gaseous liquids. In the form illustrated herewith, it is particularly adapted for the dispensing of liquids in which gases are present, such as the carbonated liquids in use with soda fountains and dispensed from an installed system, or carbonated liquids dispensed from separate containers, such as the so-called siphons. It is not limited to this purpose or use and may be used for the discharge or dispensing of any liquids in which gas is present in solution or otherwise.

One object of the invention is to provide a means or a method for permitting and controlling the discharge of the liquid in such a manner that the gases present in the liquid are retained. in. the liquid as far as possible at the time the liquid is discharged from the apparatus.

Another object is to provide such a device and to provide in it ready means for adjustment and cleaning, to permit adequate control of the size of the discharge opening and to permit ready enlargement of that opening for flushing and other cleaning action. This adjustment or cleaning means is so arranged that it may be adjusted from the outside without removing the device from its normal position of use and without taking it apart or otherwise opening it.

Other objects will appear throughout the specification and claims.

The invention is illustrated more or less diagrammatically in the accompanying drawing, wherein:

Figure 1 is a section of one form of a liquid dispensing means with thedevice of the present invention in place;

Figure 2 is a detailed longitudinal sectional View of the controlling device shown in Figure 1 on an enlarged scale;

Figure 3 is a transverse section taken at line 33 of Figure 2;

Figure 4 is a side elevation with parts broken away and parts in section illustrating the device in position in one form of siphon.

Like parts are designated by like characters throughout the specification and drawing.

I illustrates the body of one form of a draft arm. The invention may be applied to any draft arm. As shown, there are associated with the draft arm body a cap 2- and a cap 3. 2 is secured to the body by a pivot screw and 3 is screwed directly to the body by appropriate threads on each part. A valve mechanism provides means for controlling the flow of fluid through the draft arm and includes a member 5 and a handle 6 for rotating it to open and close the passage 1 through the valve assembly and the draft arm. A passage 8 communicates with the passage l and is formed within the nozzle 9 which is screwed to the body I by threads formed on each. The nozzle part 9 is interiorly threaded as at [0 to receive a controlling device.

The controlling device of the present invention comprises a portion l l exteriorly threaded as at. 52, to be received in the interiorly threaded portion 10 of the nozzle 9, and a passage '63 is formed in-this member. This passage communicates with an enlarged cavity 14, formed in an enlarged section 15. The enlarged section I5 is preferably interiorly threaded about its lower margin. The portion I5 thus forms a housing to contain a controlling member which will be described below.

Co-operating with the portion I5 is a second housing member l6 provided with an exteriorly threaded portion H which engages the threading on the interior of the portion !5. A discharging passage l8, formed in the section it, is preferably of a greater cross section than the passage Him the member H. A member I9 is positioned within the section It and is provided with one or more perforations 20. The member I9 is also provided with a perforation 2! within which is threaded a part 22 of a controlling and guiding member. The lower or outer end of this part may be notched as at 23 so that it may be rotated by a screw driver or other suitable tool and thus may be adjusted toward and from the discharging end of the passage l3. Preferably integral with the member 22 is a portion 24 provided with an inwardly facing outwardly flared or inclined annular wall member 25. A conical member 26 is formed as a part of the controlling member and preferably extends partially into the discharge end of the passage It. The discharge orifice from the passage I3 is thus given an annular shape and liquid discharged from it passes downwardly and outwardly from the passage is flowing along the surface of the cone 26, and then, reversing its direction, it flows upwardly along the inner face of the member 25. It is then discharged over the edge of this member and flows downwardly and outwardly through the per forations 20 in the member I!) and is finally discharged through the outer passage I8.

In general the device of the present invention will be used so that liquid is discharged downwardly but it is not limited to that use or position and it may be used to discharge the liquid in any direction. In the form of Figure 4, the

control device is the same as that previously shown and described, but instead of being mounted upon a draft arm or similar device, which may form a part of an installed liquid discharging system or apparatus, it is attached to a siphon 3B, which has an upwardly extending member 3| and a discharge or outlet tube 32 which may be supported directly upon the siphon, but is more often supported within a cap 33 from which a discharge portion 34 having a discharging passage 35 extends. of the passage 35 is interiorly threaded as at 36 to engage the threads l2 of the control device. Siphons are generally provided with some valve mechanism which normally acts to prevent discharge but which may be opened to permit discharge. A member 3'! is indicated diagrammatically as comprising the means for opening such a valve. This means and the valve itself are not shown in detail, as their, details form no essential part of the present invention which may be adapted to the use of almost any form of siphon, and the showing of the device herewith in connection with a siphon is merely to illustrate that possible use.

It will be realized that whereas I have herewith shown and described an operating form of my invention, nevertheless many changes might be made in the form, shape and arrangement of parts without departing from the spirit of my invention. r

While the device is shown in position in a draft arm and also in a siphon, it is not limited to these uses and may be used in any association where a device of the sort disclosed is desirable or adaptable. Also, it may be associated with any form of draft arm irrespectiveof the particular valve and controlling means, and the draft arm and assembly shown partially in Figure 1 is shown as representing merely one typical form of draft arm and its details are not described in full, as they form no essential part of the invention or of its method of operation. The tapered portion at the lower end of the passage l3 may or may not be omitted. As shown, theinclination of this tapered portion is substantially the same as the inclination of the conical portion 26, This relationship, while desirable for many purposes, is not essential, and the taper in the passages 13 might be omitted or if present its angle of inclination might differ from that of the member 26. I

The use and operation of the invention are as follows: I 7

It has been found in the past that inapparatuses for the dispensing of liquid containing gases which it is desired to retain in theliquid after dispensing, the normal valve mechanism in a siphon or draft arm, when firstopened, and sometimes after being fully opened, provides a sharp edged opening for the passage of such size thatthe liquid as it passes through the passage and over the sharp edges or edge formed in or at the beginning of or at the end of the said passage is in effect torn apart and the gases are liberated. In the device of the present invention, the final size of the discharge opening is not in any way determined by the valve mechanism. The effect of the valve is merely to control the flow of liquid toward the final discharge opening, and this final discharge opening is so arranged as to prevent the tearing action of the liquid and to retain as large a portion as possible of the gas in the liquid, either in solution or otherwise.

There is thus provided. an annular opening The outer, or discharging end formed by the member 26 and the lower end of the passage l3, whether the latter is conical or not in its lower end. Fluid passing through this opening is turned and largely reversed and flows upward along the inner walls of the outwardly flared Wall-like member 25 and passes over the edges of this member through a larger annular opening formed by the outer edge of the member 25 and by the inner surface of the housing defined by the parts 15 and I6. The action which takes place within the housing is relatively smooth and undisturbed because of the shape and dimensions of the parts described, and since even that portion of the gas which has escaped from the fluid at this stage of discharge is still within the housing, some of it is re-engaged within the liquid or entrapped or dissolved and carried along with the liquid. Thus, by reason of the arrangement and shape of the parts shown and described herewith, discharge of gas from the liquid is reduced to a minimum and some of the gas which escapes from the liquid during its passage through the system is taken up by the liquid again before the final combined discharge of the liquid and the gas through the opening I8.
